Sunny south facing smooth dome of good quality rock. Bolted routes, but bring a light rack for right routes and rigging anchors up top. Some bouldering right of the dome.
Best approached by hiking north from the north boat ramp parking lot (see Watson Lake overview for trail details). Perfect Dome becomes obvious after you leave the dirt road and hike a bit over rock and into narrow slots. It is the smooth dome with a tree at its base. Alternately, you can approach by hiking through the same canyon as Thor's Wall west to the canyon's end, Perfect Dome will be on the right.
